IEEE International conference on Image Processing

作者： Jiading Gai Yong Li Robert L. Stevenson Department of Electrical Engineering University of Notre Dame Notre Dame IN USA

Principal component analysis (PCA) is a technique that is widely used for applications such as dimensionality reduction, image compression, feature extraction and data visualization. One of the key issues in the use of PCA for modelling is that it is very sensitive to outliers since its formulation is based on Gaussian density model. Lately, more heavy-tailed distribution (i.e., Student's t-distribution) is introduced to increase the robustness of traditional PCA. But the robust version of PCA is expressed as the maximum likelihood solution of a probabilistic latent variable model. This reformulation raises the question of how to determine the optimal number of principal components to be retained. In this paper, we develop a Bayesian model selection approach to estimate the true dimensionality of the data. The proposed algorithm is based on a new Bayesian treatment of robust Student's t-distribution PCA. A simple Expectation-Maximization (EM) solver is introduced to find approximate solutions for the model. Experiments show that the proposed model achieves simultaneous optimal dimensionality selection an.d accurate principal components recovery.

Standard sleep stage classification is based on visual analysis of central EEG, EOG and EMG signals. Automatic analysis with a reduced number of sensors has been studied as an easy alternative to the standard. In this study, a single-channel electro-oculography (EOG) algorithm was developed for separation of wakefulness, SREM, light sleep (S1, S2) and slow wave sleep (S3, S4). The algorithm was developed and tested with 296 subjects. Additional validation was performed on 16 subjects using a low weight single-channel Alive Monitor. In the validation study, subjects attached the disposable EOG electrodes themselves at home. In separating the four stages total agreement (and Cohen's Kappa) in the training data set was 74% (0.59), in the testing data set 73% (0.59) and in the validation data set 74% (0.59). Self-applicable electro-oculography with only two facial electrodes was found to provide reasonable sleep stage information.

Combined thermal-LIDAR imagery for urban mapping

International conference on Image and Vision Computing New Zealand, IVCNZ

作者： Daniel O'Donohue Steven Mills Simon Kingham Phil Bartie David Park Geospatial Research Centre (NZ) Ltd. Christchurch New Zealand Geospatial Research Centre Limited Christchurch New Zealand Department of Geography University of Canterbury Christchurch New Zealand

The use of high resolution thermal imagery to represent the urban thermal landscape provides an excellent method of visualising temperature fields and relating them to real world objects. The mapping of these temperature fields provides data for further analysis and is a powerful mechanism for communicating complex ideas to the general public. Aerial thermal mapping also provides a means of locating areas of heat loss by identifying locations of higher than ambient air temperature. Traditionally, imagery has been displayed in two dimesions; this fails to realistically represent urban landscapes. This paper presents a method of obtaining high resolution thermal imagery from an aerial platform and combining it with existing elevation data for the purposes of mapping the thermal landscape of Christchurch City in 2.5 dimensions. analysis carried out on the subsequent 2 and 2.5 dimensional maps reveals the complexity of the temperature fields in the urban environment and suggests that surface temperature is not simply a function of received radiation.

Development of softwares for teaching electromagnetics

Development of softwares for teaching electromagnetics

International conference on Recent Advances in Microwave Theory and Applications, MICROWAVE

作者： Yusuf Akhtar R. Garg E & ECE Deptt. IIT Kharagpur India

Summary form only given. The students are by and large averse to electromagnetics. The reasons for this could vary from: the subject is highly conceptual, to students dislike for vector calculus, to lack of visualization of vector fields. Unlike subjects such as mechanics where one can visualize the subject through common experience, electromagnetics involve electric and magnetic fields which can be measured but cannot be seen. Electromagnetics would thus require the mental ability to visualize without which understanding of concepts not readily apparent from equations, would become difficult; leading to disinterest in the subject. Although the electromagnetic fields cannot be seen, they can be at least computed and presented graphically in colour; and thus help in visualization. With these points in mind, we have tried to understand and develop tools for simulation and visual presentation of certain physical phenomenon in electromagnetics. One may use computational methods to develop softwares specifically for teaching. The computational techniques such as finite difference, FDTD, FEM, MoM, etc may be employed for this purpose. The FDTD method is found to be most interesting for teaching because it produces animation of wave propagation; which is the basis of high frequency electromagnetics. The development of softwares based on FDTD is a highly skilled job, and the simulation results differ slightly from the expected results because of discretization errors. We have used Matlab for generating data related to various physical phenomenon, and used its movie feature to play those frames repeatedly to generate the effect of wave propagation, reflection, transmission etc in one-dimension. The basic approach used for the development of softwares will be presented.

Most practical signal processing problems have to deal with uncertainties, e. g., due to noisy input data. Usual strategies to do this are based on estimating these uncertainties by statistical methods in advance. For some systems with multi-staged signal processing it is possible to identify these estimates at runtime and to relate a degree of certainty to them. If such degrees of certainty are known for input signals, e. g. by earlier stages of processing, this knowledge can be used to get a more robust or accurate result in classification tasks in the later stages, even if they vary at runtime. In this paper we thus introduce an approach to extend support vector machines to incorporate such known uncertainties at runtime, given as certainty degrees. Based on the known certainty of each input, classification depends more on certain inputs and gradually less on uncertain input data. This is done by changing the decision (kernel) function online, i. e., during operation. An artificial two-dimensional dataset is used to visualize the effects of this extension. And the application to three different datasets is a first benchmark showing that the resulting classification quality increases when known uncertainties are considered.

The traditional sampling method for environmental monitoring of aerosols is time consuming and expensive. Remote sensing data have been widely used in environmental studies like land cover change, flood observation, environmental pollution monitoring. This study is dealing with obtaining water pollution using Landsat TM data over Penang Strait, Malaysia. With the availability of remotely sensed and in situ data sets the derivable geophysical parameters is sediment (suspended matter) concentration. The proposed algorithm is based on the reflectance model that is a function of the inherent optical properties of water, which can be related to its constituent's concentrations. Regression and accuracy analysis is performed using SPSS analysis software. Water samples locations were determined using a handheld GPS. The digital numbers were extracted corresponding to the ground-truth locations for each band was converted into radiance and reflectance and later used for the calibration of the developed algorithm. The efficiency of the present proposed algorithm, in comparison to other forms of algorithm, was also investigated. Based on the values of the correlation coefficient (R) and root-mean-square deviation (RMS), the proposed algorithm is considered superior. The proposed algorithm is considered superior to other tested algorithms based on the values of the correlation coefficient, R=0.94 and root-mean-square error, RMS=5 mg/l. The calibrated TSS algorithm was used to generate the water quality map. The TSS map was color-coded and geometrically corrected for visual interpretation.

Persistent digital media extend content beyond immediate ephemeral interactions and conversations. Systems such as email, instant messaging, digital kiosks, social networking sites, and wikis collect large quantities of electronic data and store it for later use. How will people encounter and understand these data now and later? How do people move between the ephemeral and persistent in everyday settings? Can persistence exist beyond visible data? We have been exploring these questions through field studies in an urban setting and an online game. This paper is a preliminary exploration of issues that have arisen in our empirical research on the ways people move between persistent and ephemeral media. In this paper, we investigate an expanded concept of persistence which renders ephemerality as a complementary element during processes of communication and interaction. Drawing on previous work and findings from our empirical studies, we argue that seeing persistence and ephemerality as intimately linked opens up possibilities for analyzing and creating new design spaces and forms of interaction with digital media.

IEEE International conference on Development and Learning, ICDL

作者： Yuuya Sugita Jun Tani RIKEN Brain Science Institute Saitama Japan

We propose a sub-symbolic connectionist model in which a compositional system self-organizes by learning a provided set of goal-directed actions. This approach is compatible with an idea taken from usage-based accounts of the developmental learning of language. The model explains a possible continuous process underlying the transitions from rote knowledge to systematized knowledge by drawing an analogy to the formation process of a regular geometric arrangement of points. An experiment was performed using a simulated mobile robot reaching or turning toward a colored target. By using an identical learning model, three different types of combinatorial generalization are observed depending on the provided examples. Based on the experimental results, a dynamical systems interpretation of conventional usage-based models is discussed.

作者： Hanane H. Mirza Hien D. Thai Zensho Nakao Department of Electrical and Electronics Engineering University of Ryukyus Okinawa Japan

The digitalization of e-learning sources makes it an easy target for frauds, conterfeiting and content stealing. In this paper we present a new technique to deal with the security problems of e-learning content, its authentication and digital right management. The proposed technique is done by inserting a digital logo image, which serves as watermark signals, in the audio stream of e-learning material. This technique is based on modulated complex lapped transform that was selected for its audio reconstruction properties and the extraction of the watermark is performed using an independent component analysis algorithm. To demonstrate the effectiveness of the proposed method, a real world implementation has been done and the algorithm shows quite good visual and audible quality in watermarked content, as well as a high robustness against common signal processing attacks.

Recently, many vision-based robotic applications such as visual SLAM (Simultaneous Localization And Mapping) and autonomous navigation have achieved good performance using visual features. In these applications, robust feature tracking plays an important role, e.g., in scene recognition for autonomous navigation and in data association for visual SLAM. In this paper, we propose a hierarchical outlier detection algorithm for robust feature tracking;the algorithm uses a simple window-based correlation (NCC) and enforces angular and scale constraints. The proposed algorithm maximizes the inter-cluster score and detects outliers that do not satisfy the angular constraints. The remaining outliers are detected by enforcing scale constraints using SIFT descriptors. The proposed algorithm is efficient and particularly useful for scene recognition, in which an image corresponding to a query image is searched among data images. Experimental results demonstrate that the proposed algorithm is robust to outliers and image variations such as scale changes. One of the main applications of the proposed algorithm is global localization due to its low computational complexity and robustness to outliers.
